IMPROVEMENT IN COOK-STDVES.

Specification forming part of Letters Patent No. 171,649, dated January 4, 1876; application filed December 11, 1875.

To all whom it may concern Be it known that we, EZRA E. BROWN and of Montour and State of Pennsylvania, have invented certain new and useful Improvements in Cook-Stoves; and we dohereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to'make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of our invention consists in the construction and arrangement of a cookingstove whereby air may be heated so as to be,

as will be hereinafter more fully set forth.

In the, annexed drawing, Figure l is a plan view of a cooking-stove, embodying our invention. Fig. '2 is a side elevation, and Fig.

3 a longitudinal vertical section of the same.

A represents the fire-pot, B the oven, and G the top plate, of" any ordinary cookingstove. D. is the fire-back, made of cast-iron, and cast hollow, with apertures a leading from near the top of said hollow fire-back into the oven B. E is the back "hearth-plate, provided with apertures 12 directly under the door into the oven under the fire-chamber, and in said door is a damper, valve, or regis-" ter, d, as shown in Fig. 2. Both sides of the stove may be provided with such valve.or register d. Cold air passes in through the valves or registers 61 into the lower front part of the oven and up through the apertures b into the hollow fire-back D, in which the air becomes thoroughly heated. From the hollow fire-back the heated air passes through the apertures a into the top part of the oven,

and out of the oven through a damper, h, up I through an independent flue, H, into the heating-pipe, which is intended to surround the ordinary smoke-pipe. The heating-pipe may be carried to any part desired to be heated.

Letters Patent, is

1. In a cooking-stove, the combination of the hollow back D, open at the lower end, the back hearth-plate E, having aperture 12 directly under the lower end of the'fireback, whereby the air is taken from the oven, heated, and returned to the oven, substantially as and for the purposes set forth.

2. [n a cooking-stove, the combination of the oven'door G with register at, back hearthplate with apertures b, hollow fire-back D, with aperturesa, and flue H, with damper h, substantially as and for the purposes herein set forth.

In testimony that we claim the foregoing I as our own we aflix our signatures in presence of two witnesses.
